2Dr Zr-2 Blazer build. GFY :)

I picked up a 99 Zr-2 Blazer. 100k on it. Got a good deal. But it needed some work But doesn't everything?

End game is four death penalty 18s on two 40.1s. Still waiting on two of the 18's.
Right now I have Four D3100's, need to pick up one for my custom busbars. I have a mechman 370a elite alt, 8 runs of 0ga. Put a set of tantric comps in. Lots of random ish.
